Administration of the MapR-DB is done primarily via the command line (maprcli) or with the MapR Control System (MCS). Regardless of whether the MapR-DB table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. MapR-DB administration is associated with tables, columns and column families, and table regions.

The MapR Data Access Gateway is a service that acts as a proxy and gateway for translating requests between lightweight client applications and the MapR cluster. This section describes considerations when upgrading the service, how to modify configuration settings, and how to administer and manage the service.

Disabling Automatic Central Configuration

Automatic central configuration is enabled by default. You can configure central
configuration to stop automatic runs of the pullcentralconfig script by
editing warden.conf and setting the following variable to
false: centralconfig.enabled=false

To make the change take effect, restart Warden:

root$> service mapr-warden restart

Note: When
automatic central configuration is disabled, you can still manually run the
pullcentralconfig script to push the latest configuration files to
nodes in the cluster.
